EJNTT FKQEQ JOHN H. CRAIG, OF CINCINNATI, OHIO.

REFRIGERATING VESSEL.

To all whom it may concern Be it known that 1, JOHN H. CRAIG, a citizen of the United States, residing at Gincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Refrigerating Vessels, of which the following is a specification.

This invention relates to refrigerating vessels and particularly to a cabinet designed for the storage of ice cream, an object of the invention being to provide means whereby under the action of the refrigerant and the construction of the cabinet the ice cream may be maintained in a frozen condition for a considerable length of time.

Another object of the invention is to provide a casing which will readily accommodate itself to packing or storing cans of different sizes.

Another object of the invention is to provide a refrigerating cabinet wherein means are employed for effectually sealing the joint between the storage can and the closure of the cabinet so as to prevent salt or the like from the refrigerant from entering said can.

In the drawing forming a portion of this application, and in which like numerals of reference indicate similar parts in the several views :Figure 1 is a perspective view of the cabinet. Fig. 2 is a perspective view of the closure. Fig. 3 is a perspective view of the can rest. Fig. 4 is a vertical section through the cabinet.

The cabinet comprises a casing 1 having spaced outer and inner walls 2 and 3, a con necting annular top wall 4 and spaced bottoms 5 and 6, the space between all of the companion walls being filled preferably with cork, mineral wool, asbestos or like heat insulating material to prevent the absorption of heat and thereby increase the refrigerating efliciency of the structure. At the lower end the vessel 1 is provided with an opening 7 in which is fitted a drain pipe 8, the latter having detachably and preferably threadedly connected therewith a cap 9 which may be removed at the will of the operator to open the drain pipe and thereby permit the water to be discharged from the refrigerant chamber of the vessel.

A can rack 10 is removably mounted in the refrigerant space 11 of the vessel 1, being preferably provided with an annular flange 12 for a purpose to be hereinafter described. The can rack is provided with feet or supporting means 13 which preferably extend Specification of Letters Patent.

in the direction of the lower corner of the vessel 1 so as to engage against the inner walls 3 and the adjacent portions of the bottom 5 whereby the rack is held spaced from the latter as is understood. The can rack removably receives a storing can 14 which is designed to receive the ice cream to be refrigerated. The flange 12 of the can rack embraces the lower walls of the storing can and the flange acts in a measure toward holding the can against lateral displacement in the refrigerating space of the vessel.

' lVith a view to assisting in the action of the flange 12 toward holding the storing can against lateral displacement and also with a view to securely holding the can against longitudinal movement and to effect an air and liquid tight connection at the upper end of the refrigerant chamber I provide an adjustable member 15 whose walls are insulated by suitable material 16 as shown. The wall 17 of said adjustable member is threaded so as to adjustably accommodate itself to a corresponding thread 18 upon the wall 3 of the vessel 1. The member 15 has formed therein a central opening 19 which removably receives a cover 20 having spaced walls 20* and 20 with insulating material 20 therebetween, the cover being disposed in a di rect vertical line with the storing can let and having a flange 21 thereon which is designed to engage against the top of the member 15 whereby its adjustment in the opening 19 is limited in one direction. A. knob 22 on the central portion of the insulating closure 20 may be graspedby the hand to facilitate the adjustment of the closure.

The member 15 which in a measure forms a closure for the refrigerant chamber of the vessel 1 is provided with manipulating handles 24 whereby the member can be readily adjusted vertically in the vessel 1 and compelled to engage frictionally against the top of the storing can 14, thereby efiecting a perfect liquid and air tight connection at this point.

It will of course be understood that the can rack 10 may be made of any size to accommodate a storing can of a corresponding size. It is also said that the closure forming member 15 will be correspondingly made according to the size of the storing can which is placed in the vessel.

In use the drain pipe 8 is sealed by the cap 9. The rack 10 is then placed in the bottom of the refrigerant space 11 of the vessel 1. The ice cream can la is then placed in the rack 10 as shown in Fig. 4; and the space subsequently filled with a refrigerant such as ice. The closure 15 is then adjusted upon the thread 18 until the desired contact of the same is made with the upper edge of the storing can to effect a proper joint at this point. The closure 20 is then placed in the opening 19, whereupon the cabinet is rendered sealed in such manner that the ice cream may be held or maintained in a highly frozen condition for a long length of time.

I claim A refrigerating cabinet comprising a casing having an interiorly threaded portion, a rack removably mounted in said casing and having its sides and bottom spaced from the adjacent walls of the casing, a can removably mounted in the casing and having its bottom portion fitting within said rack a threaded member adjustable in the threaded portion of the casing and adapted to bear against the upper edge of the can and to hold the latter against tilting movement on the rack and to seal the joint between the memher and the can, said member having an opening therein in line with the can and a closure removably fitting the opening and serving to cover the upper end of the can.

In testimony whereof I aflix my signature in presence of two Witnesses.

JOHN H. CRAIG.
